Digging into perovskite efficiency

A research group at the Helmholtz Zentrum Berlin has conducted an in depth analysis looking at the crystalline structure of methylammonium lead iodide, one of the most promising perovskite materials for solar cell production. The group made a series of discoveries which they hope will help to unlock some of the remaining issues in creating cells that are both stable and highly efficient.

Mounting interest in gravity-based storage solutions

Austrian researchers have proposed gravitational energy storage for locations with low demand. The scientists claim the system they are suggesting can be combined with other forms of storage as well as renewables, costs $50-100 per megawatt-hour of stored energy and $1-2 million per megawatt of installed capacity to develop.
